Architecture
The South Tower vertical expansion at Sinai Hospital will add three stories onto the existing three-story tower, retaining the shape of the existing footprint. In addition, a six-story link enclosing a four-story atrium lobby will connect the existing North Tower to this brand new vertical expansion. A helipad and elevator tower round out the new construction. Each floor will have its own unique function. The fourth floor will house the ICU, OR, Pre-Op, and PACU. The fifth floor will be the future home of traumatic brain injury care and sterile processing. Lastly, the IMC will be on the sixth floor.

Building Envelope
The exterior façade of the vertical expansion will resemble the façade on the existing three-story tower. It will consist of a water-managed exterior insulation finishing system (EIFS) with control joints. The EIFS will be over glass-mat-faced gypsum sheathing on 6” structural metal studs with glass fiber batting insulation, vapor barrier, and gypsum wallboard. Glazed aluminum framing will be used on part of the vertical expansion and on a majority of the link. Exterior glass (vision and spandrel) will be double pane, low-e, and heat strengthened. Roof construction will consist of a roof membrane on rigid insulation and metal decking. In addition, the fourth floor will have a green roof garden.
*Historical Requirements not applicable
Mechanical System
Two new custom air handling units serve the expansion. A chilled water plant in the penthouse consisting of a 2,000 ton centrifugal chiller, cooling tower, and chilled and condenser water distribution pumps is required to provide additional infrastructure. Existing heating hot water, steam, domestic water, and medical gas mains are extended to the new air handling units. Air systems for both supply and return are variable air volume and medium pressure. Infectious isolation rooms have a dedicated isolation exhaust system.
Electrical System
The penthouse will house a double-ended 3,000 kVA, 13.2 kV 480Y/277V substation to provide power for the three additional levels of the vertical expansion. A 2,500 kVA 13.2 kV 480Y/277V substation serves the chiller and associated cooling tower and pumps. Normal power to each floor is distributed at 480V and steps down to 208Y/120V via dry-type transformers. All lighting fixtures are 120V, primarily fluorescent.
Structural System
The South Tower vertical expansion will be supported by the existing grade beam foundation system. The frame construction is concrete, consisting of post-tensioned beams, reinforced walls, and structural slabs. The link is also supported by a grade beam foundation system. Its frame is concrete as well with tendon support.
